The ADG714/ADG715 are CMOS, octal SPST (single-pole, single-throw) switches controlled via either a 2- or 3-wire serial interface. On resistance is closely matched between switches and very flat over the full signal range. Each switch conducts equally well in both directions and the input signal range extends to the supplies. Data is written to these devices in the form of 8 bits, each bit corresponding to one channel.
